Inconsistent use of single-line vs multi-line closures across codebase
Category
Maintainability Code Snippet
data.iter().each(k => s += " {k}") Recommendation
Establish consistent guidelines for when to use single-line vs multi-line closures. For example:
Use single-line when the operation is simple and fits in <80 chars
Use multi-line when there are multiple statements or line length exceeds limit Reasoning
While the changes make the code more concise, having inconsistent styles across the codebase can make it harder to maintain. Clear guidelines help developers make consistent choices.
Chain of method calls without line breaks may reduce readability
Category
Maintainability Code Snippet
data.iter().each(k => s += " {k}") Recommendation
Consider breaking long chains into multiple lines for better readability:
data
.iter()
.each(k=>s+=" \{k}")
Reasoning
While shorter code is often better, method chaining on a single line can become hard to read if there are many operations. Breaking into multiple lines improves scanability while maintaining the concise logic.
String concatenation in loops could be inefficient for large datasets
Category
Maintainability Code Snippet
s += " {k},{v}" Recommendation
Consider using a string builder or collecting into an array and joining at the end if this needs to handle large datasets Reasoning
String concatenation in loops can lead to many intermediate string allocations. While fine for small test cases, this pattern could cause performance issues at scale.
